  • Patent number: 9037355
    Abstract: A ground engaging vehicle including a tool having a moving member and a control system controlling a speed of the moving member. The control system includes an adjustable proportional control and a triggering control. The adjustable proportional control creates a signal to thereby select a direction and a speed of the moving member. The triggering control setting the direction and/or the speed dependent upon the signal resulting in a set direction and a set speed, the triggering control subsequently setting the speed to zero.

  • Patent number: 8862274
    Abstract: A work machine (10) comprises an operator interface (30), an auxiliary electro-hydraulic circuit (22 or 322) adapted to operate a hydraulic actuator (16) of an auxiliary tool (12) when the auxiliary tool (12) is attached to the work machine (10), and a controller unit (24) that communicates with the operator interface (30) and the auxiliary electro-hydraulic circuit (22 or 322). The controller unit (24) is adapted to receive from the operator interface (30) an electrical setpoint signal representative of a flow setpoint selected by an operator via the operator interface (30), and electrically operate the auxiliary electro-hydraulic circuit (22 or 322) so as to output flow from the auxiliary electro-hydraulic circuit (22 or 322) to the auxiliary tool (12) at a substantially constant magnitude represented by the flow setpoint. An associated method is disclosed.

  • Patent number: 8504250
    Abstract: A work vehicle comprises a mechanical front wheel drive (MFWD) and a MFWD switch associated with the MFWD for selectively activating the MFWD. The MFWD switch may be a 3-position switch comprising a momentary-ON position, a maintain-ON position, and a maintain-OFF position. The MFWD switch may be, for example, a 3-position rocker switch.

  • Patent number: 7666116
    Abstract: Method and differential-lock control apparatus for differential lock control are disclosed. A control unit is arranged for communication with an engine speed sensor, a differential-lock activation control, and a differential lock. The control unit is adapted to allow for reduction of an engine speed to a desired engine speed if the engine speed is at least a threshold engine speed in response to receipt of an activate-differential-lock request signal, and adapted to subsequently output an activate-differential-lock control signal to the differential lock so as to command activation of the differential lock.

  • Patent number: 7388471
    Abstract: In accordance with the present invention, an anti-theft system includes an input device and a processor having an associated memory, the memory including instructions executable by the processor to activate the anti-theft system in response to receiving an authorization code from the input device and, when the anti-theft system is activated, to lock the engine in response to receiving one of a user code and a master code from the input device.

  • Publication number: 20080131252
    Abstract: A work machine includes a machine frame, a loader and an electronic level indicator. The loader includes a loader frame coupled with the machine frame, a pair of booms pivotally carried by the loader frame, and a bucket pivotally carried at a forward end of the booms. An electronic level indicator includes a first indicator providing an indication of a relative angular orientation between the loader frame and at least one boom. A second indicator provides an indication of a relative angular orientation between the bucket and at least one boom. A controller is coupled with the first indicator, the second indicator and a visual indicator. The controller receives an input signal from each of the first indicator and the second indicator and actuates the visual indicator to indicate when the bucket is level.
